variables?

[Socco]

I want to be able to do something like this;

#act {You get < salvage >}{#outp {white} SALVAGE};#var salvage 1}
#act {You get < salvage >}{#outp {white} SALVAGE};{$if salvage=1}{#var salvage 2}}
#act {You get < salvage >}{#outp {white} SALVAGE};{$if salvage=2}{#var salvage 3}
#act {$if salvage=3}{recall}


Anyone know how I'd go about do that?
Making it so every 3x salvage it recalls
